I would say make sure your hair is sopping wet and combed thru as smoothly as possible. Wet your rollers too. You wanna wrap the hair taut too. The tighter the roller, the smoother your ng should be but some hair types just aren't going t/b smooth, no matter what u do. In that instance, I wouldn't try to fight it... What are u using to rollerset? Leave in, setting lotion, serum?
